ABSTRACT
@#Retinoblastoma very rarely presents as vitreous haemorrhage. We are presenting a case of atypical presentation of retinoblastoma in a 3-year-old girl. She initially came with right eye vitreous haemorrhage of unknown cause. B-mode ultrasound showed dense vitreous opacity without evidence of mass. Initial MRI Brain/Orbit was inconclusive. Diagnostic vitrectomy was performed and noted thickened abnormal retina which was suspicious for retinoblastoma. The parents refused for enucleation for diagnostic histopathological examination and opted for conservative management. Repeated MRI Brain/Orbit done six months later showed disease progression through optic nerve involvement and suggestive of retinoblastoma. The parents were re-counselled for enucleation however refused and defaulted. 2 months later, the child was brought back with proptosed and disorganized eye. This time, they agreed for intervention. The patient underwent three cycles of chemoreduction therapy before enucleation. After enucleation, she received six cycles of adjuvant chemotherapy. She was well with no disease recurrence at two-year post treatment.
ABSTRACT
@#AIM: To study the clinical characteristics of vitreous hemorrhage associated with retinal tears, so as to provide suggestions for early intervention and improving the prognosis of patients.<p>METHODS: This was a retrospective study. Totally 105 patients(105 eyes)with vitreous haemorrhage associated with retinal tears treated at our hospital from December 2016 to December 2018 including 54 males and 51 females, of who the clinical characters, therapeutic effcet and prognostic facors were retrospectively analyzed.<p>RESULTS: Among the 105 eyes(151 retinal tears), 82 tears were located in the superotemporal area(54.3%), 28 tears were located in the superonasal area(18.5%), 27 tears were located in the inferior temporal area(17.9%), and 14 tears were located in the inferior nasal area(9.3%). The shape of the retinal tears was mostly horseshoe(77.5%). The diameter of the tear was between 1/8-4 papillary diameter(PD), most commonly is 1 PD. Seventy-six patients(72.4%)had visual acuity better than or equal to their preoperative vision. There was no significant difference in corrected visual acuity pre-and postoperative(<i>P</i>>0.05), and there was no statistically significant improvement in visual acuity between the buckling procedure group and the vitrectomy group(<i>P</i>>0.05).<p>CONCLUSION: Retinal tear is an important cause of vitreous haemorrhage. Retinal tears were mostly located in the superotemporal area with horseshoe shape. A comprehensive understanding of the clinical characteristics of rhegmatogenous vitreous haemorrhage helps to detect tears early and avoid serious complications.Patients had preoperative best corrected visual acuity(BCVA)(LogMAR)less than 1.6 and light perception less than 1 m, have poor postoperative vision, as do patients with retinal detachment involving the macula especially along with proliferative vitreoretinopathy(PVR).
ABSTRACT
The increase in prevalence of diabetes in India is one of the leading causes of blindness due to micro vascular and macro vascular complications. The complications in retina and kidney are due to damage of small vessels. Studies have shown significant association between diabetic retinopathy and diabetic nephropathy. In our study, we are discussing the complications during intra and post-operative period and also both anatomical and functional outcome in these patients after vitrectomy for proliferative diabetic retinopathy. Both eye and kidney share same vascular pattern. One pre-existing condition can be followed by the other condition due to similar microvascular damage. We wanted to evaluate the outcome of vitrectomy in proliferative diabetic retinopathy patients associated with chronic kidney disease.METHODSThis is a retrospective study done at Sarojini Devi Eye Hospital, Telangana State, South India, over a two-year period from June 2017 to June 2019. Data was collected from old medical records of our institute, from patients who presented to Retina Dept. with various complaints. They were examined in detail, documented and treated based on clinical presentation after clearance from physician. Patients presented with different ocular manifestations like non-resolving vitreous haemorrhage, focal tractional retinal detachment, multi focal tractional retinal detachment like broad based, table top, combined retinal detachment and tractional maculopathy. Patients underwent pars plana vitrectomy with or without silicone oil endotamponade.RESULTSPrognosis in these patients was good only in cases of non-resolving vitreous haemorrhage and focal tractional retinal detachment (47.61%) whereas in cases like multifocal retinal detachment cases outcome was favourable (42.82%) but patients with combined retinal detachment (9.52%) had poor anatomical and visual outcome.CONCLUSIONSManagement of these patients is very difficult when there is severe proliferative diabetic retinopathy with multiple broad vitreo retinal adhesions. Outcome is very poor particularly in patients of severe proliferative diabetic retinopathy associated with chronic kidney disease and coronary artery disease due to intra operative complications
ABSTRACT
Background: Eales’ disease is an idiopathic retinal vasculitis characterized by retinal infl ammation, ischemia, and neo-vascularisation. It frequently causes massive vitreous haemorrhage and retinal detachment leading to blindness. Although the exact etiology is unknown, this condition is considered to be a consequence of hypersensitivity reaction to tubercular protein due to previous Mycobacterium tuberculosis (M. tuberculosis) infection. This study is aimed at the detection of association of M. tuberculosis in patients with Eales’ disease. Materials and Methods: A prospective case-control study was undertaken in 65 clinically diagnosed cases of Eales’ disease. Patients with proliferative diabetic retinopathy, neo-vascular proliferation, macular oedema, premacular fi brosis and tractional retinal detachment were taken as controls. M. tuberculosis DNA was detected (MPT64 gene by polymerase chain reaction, PCR) in patients with Eales’ disease. Clinical symptoms along with tuberculin skin test (TST) and erythrocyte sedimentation rate (ESR) were used as gold standard for comparing results of PCR. Result: PCR positivity was found in 12 (38.7%) patients with Eales’ disease. The PCR positivity was signifi cantly associated with the patients with high TST reading and high ESR values. Conclusion: Patients with a high TST reading and ESR value and a positive PCR in vitreous samples have a high likelihood of having M. tuberculosis as an etiology.
ABSTRACT
A 24-year-old Chinese gentleman presented with two weeks history of sudden floaters in his right temporal visual field associated with blurring of vision. This ex-smoker also reported chronic, bloody cough for two years and recent pleuritic chest pain. Examination revealed a thin patient with right eye visual acuity of 6/18 associated with optic nerve dysfunction, optic disc swelling and macula star, retinal vasculitis and retinitis. Despite anti-tuberculosis medication and corticosteroids, he developed neovascularisation. Subsequent vitreous haemorrhage necessitated trans pars plana vitrectomy, membrane peeling, endolaser and silicone oil injection. Final visual acuity was 6/9 with quiescent retinopathy.
ABSTRACT
cases of vitreous haemorrhage secondary to Eales′ disease were selected for vitrectomy. According to the duration of vitreous haemorrhage, the patients were divided into two groups : Group 1 (20 eyes)-early vitrectomy group with a duration between 3 to 6 months; Group 2(20 eyes)-deferred vitrectomy group with a duration of more than 6 months . All the patients were followed up for a minimum period of 3 months following vitrectomy. The eyes in Group 1 showed a preoperative ultrasonic picture of complete posterior detachment, a final visual acuity of 0.6 or better in 13(65%) was achieved in mild vitreous organization on kinetic echography. Poor visual outcome in the deferred group was secondary to cystoid macular oedema, macular scar, macular pucker formation and macular degeneration. Improved visual outcome in the early vitrectomy group is probably due to haemorrhage and its products which have no time to damage the macula and to advance into macular traction and cystoid macular oedema.
